Patent FR-2560383-A1 (FR)
Title: Method and machine for abrasion testing
Inventor: BLOUET JEAN
IPC: G01N3/56
Filed: 1983-12-07
Abstract: The present invention relates to a method and a machine for abrasion testing. The method, consisting in activating friction means 107 of a to and fro horizontal movement against a trial face 23 in the presence of a liquid or pasty abrasive suspension, in a vessel 4, 5, is characterised notably in that the friction means 107 are prevented from tipping during the to and fro movement and in that agitation of the suspension in the vessel 4, 5 is performed independently of the agitation which can result from this movement, so as to ensure homogeneity of the presence and of the composition of the abrasive suspension without making the test conditions deviate from real-life conditions.
